1. Definition of a Sentence:
   • A sentence is a group of words that expresses a complete thought. Every sentence has two main parts: the subject and the predicate.
2. What is a Subject?
   • The subject of a sentence tells who or what the sentence is about. It is the person, place, thing, or idea that is doing or being something in the sentence.
3. Complete Subject vs. Simple Subject:
   • The simple subject is the main word or words in the subject that tell exactly who or what the sentence is about.
   • The complete subject includes the simple subject and all the words that describe or modify it.
4. Identifying the Complete Subject:
   • To find the complete subject, ask yourself “Who or what is this sentence about?”
   • The complete subject will include the main noun (simple subject) and any words that describe it (like adjectives, articles, or phrases).
